Σελίδα ii - SON, in the office of the Clerk of the Southern District of New. York.
Σελίδα 12 - It was also shown in the same article, that the differential of the sum of any number of functions is equal to the sum of their...
Σελίδα 129 - Fig. 52, the point A be kept fixed and the point B moved along the curve until it coincides with A, the secant AB becomes a tangent to the curve at the point A. Two curves are said to be tangent to each other at a point when they have a common tangent at that point. If a straight line is tangent to a plane curve, the tangent will lie in the plane of the curve. This is evident since the secant...
Σελίδα 28 - If u represent a function of x which it is possible to develop in a series of positive ascending powers of that variable, then will that development be where the brackets indicate the values which the inclosed functions assume when x equals zero.
Σελίδα 3 - If both members of the last equation be divided by h, we shall have u' — u •which expresses the ratio of the increment of the function to that of the variable.
Σελίδα i - ELEMENTS OF THE DIFFERENTIAL CALCULUS ; comprehending the General Theory of Curve Surfaces, and of Curves of Double Curvature. Revised and corrected by MICHAEL O'SHANNESSY, AM 1 vol.
Σελίδα 10 - Zdv -\- vdz, butt' = wy; therefore, by (3), do = ydw + wyd ; consequently, by substitution, iln = zydw + ziody + wydz . . . (4), and it is plain that in this way the differential may be found, be the factors ever so many ; so that, generally, to differentiate a product of several functions of the same variable, we must multiply the differential of each factor by the product of all the other factors, and add the results.
Σελίδα 16 - The differential of the logarithm of a function is equal to the differential of the function, divided by the function itself.
Σελίδα 201 - As an example, let it be required to find the equation of the inferior surface of a winding staircase, the aperture or column round which it winds being cylindrical.
Σελίδα 143 - F' (x) is the trigonometrical tangent of the angle between the axis of x and the tangent to the curve at the point (x, y). Art. 38. Let...
